Introduction - Defenition

• What is SOA?
• Service-oriented architecture (SOA) is a
  strategy that implements business functions by
  orchestrating reusable business services.
• Modular Programming/Object Oriented/Component
  Based Development/
• Is SOA different?

Introduction

• Why do companies choose for SOA?
• Benefits for the business
• Flexibility
• Cost reduction
• Agility
• Quicker to the market
• Technical benefits
• Loose coupling
• Platform independent
• Use of standards (SOAP,Rest,SCA,...)
• BP more transparant

Challenges for testing (1)
Business Processes
Team B

Vendor (Poland)
Team A

• Complexity
• Communication between services
• Communication with different teams/different
  locations
• No user interface

• Complexity
• Do you need to test everything?
• Vendors
• Reused services
• A lot of changes
• High frequency of changes

How to tackle these challenges?

• TMap Next
• 4 essentials
• BDTM
• Structured Test Process
• Complete Toolbox
• Adaptive

16
First essential BDTM
17
First essential BDTM

• BDTM
• Product risk analysis
• SOA Quality Characteristics

18
First essential BDTM

• Product Risk Analysis
• Complex task!
• Organsation and client are responsible
• Who participates in product risk analysis?
• Client, Senior user, Developer, Project manager,
  
• Some typical product risks
• Defective cluster of services
• Internet
• External use
• Not using the standards

19
First essential BDTM

• SOA Quality Characteristics
• Reusability
• Backwards compatibility
• Integration
• Interoperability

20
First essential BDTM

• SOA Quality Characteristics
• Security
• Performance
• per service
• per business process

Business Processesc
21
First essential BDTM

• Advantages of BDTM
• Total test effort is related to the risks
• You cant test everything
• Client is involved. Test process matches the
  needs and requirements of the organization
• Service-oriented architecture (SOA) is a
  strategy that implements business functions by
  orchestrating reusable business services.
• gt Business Driven

22
Second essential Structured Test Process

• Testing Life Cycle per Service

• Resulting in many short test cycles

23
Third essential Complete Toolbox

• Business Processes
• Conventional tools
• Services
• SOA-tools
• Isolation

Business Processesc
24
Third essential Complete Toolbox

• Test Automation
• SOA Test Tool
• Advantages of Test Automation
• Quicker to the market by automated regression
  tests
• SOA stimulates the reuse of services
• Reuse automated tests
• Business processes can change fast
• gain time by automating the regression test
• Backwards compability tests can be automated

25
Third essential Complete Toolbox

• Vendors

Rational Tester for SOA Quality
SOATest
SOAP UI
GH Tester
- HP Service Test - HP QuickTest
TesterMaker

• Silk Test
• Silk Performer SOA Edition

26
Third pijler Complete Toolbox

• SOA Governance
• Tools to support the SOA governance!
• (more then 50 services)
• Visualisation

27
Third essential Complete Toolbox

• SOA Governance
• Service Registry
• Service description (logic, quality, delevery
  conditions)
• Ownership
• Consumers
• Metrics and templates
• Defect management flows

28
Fourth essential Adaptive methode

• In all previous essentials
• Ex

29
Conclusion

• Is SOA Testing different from traditional
  software testing?
• YES
• No User interface
• Services in a chain
• Governance is extremely important
• NO
• TMAP Next
• Same structured test process
• gt Be adaptive
